The first impression was good, enough space and finally a place where you can let the hamster run sometimes a few minutes unattended. But to our surprise, toppled the first impression in the first few hours. At first we thought our Hamster climbs through the accessory out. But it was not so, he simply put on the braces up and already the obstacle was removed, The first Hamster hiding in the room we just eliminated, you do not believe what these little animals can hide everything in such a short time. Funny, the search was for the hamster, but the enclosure not served its purpose, we will send it back now .....
